Description
Technical Field
The invention relates to the technical field of campus one-card cards, in particular to an intelligent retrieving and calling device and method of the campus one-card cards.
Background
The campus card is to complete cash transaction and identity recognition and confirmation in some occasions by using an intelligent IC card in the life range of schools. The IC card integrates a book borrowing card, an on-machine card, a meal card and a wallet, and achieves the purpose of 'one card is in hand and going to the campus'. The system brings convenience to the work, study and life of teachers and students, enables various management works of colleges and universities to be more efficient and convenient, realizes the management of daily activities of teachers and students, and provides important information for teaching, scientific research and logistics services.
The campus smart card system platform is one of the most basic platform facilities in the digital campus general planning, and forms a core framework platform of the whole digital campus together with a shared data and exchange platform. The campus card system comprises two layers, on one hand, based on the powerful functions of the campus computer network; on the other hand, the intelligent IC card is adopted to realize extremely convenient identity recognition, account management and data acquisition. The campus one-card system becomes an important component in the informatization construction of all colleges and universities, is widely applied to all business departments and teaching departments, realizes the intellectualization and informatization of the management process, improves the comprehensive management level and the work efficiency of the colleges, and forms a higher-level campus management system for comprehensively managing the affairs in the colleges and universities. Meanwhile, as an important component of digital campus construction, the campus card system integrates comprehensive management and financial service of a school park, is a basic project for realizing campus informatization, and is one of important tools for realizing management and promotion of schools.
The campus card brings convenience to teachers and students, and meanwhile, the dependency of the teachers and students on the campus card is increased. The campus card is not used for basic life services in the campus of colleges and universities, however, the campus card is small in size and is used frequently, and the phenomena that the campus card is lost and is difficult to retrieve are common and serious.
According to investigation, the existing certificate retrieval methods mainly comprise the following steps:
1. retrieving lost and found places in schools;
2. the lost information is released and recovered through an instant communication tool (such as a friend circle and the like);
3. the other person picks up the contact and sends back the contact;
4. and (4) self-charging card.
No matter which mode, all have the time cycle length, the circulation process defect such as more complicated, waste time and energy, and have risks such as robbing and brushing, faking and leading, personal information reveals. Therefore, a new and feasible solution is needed.
